Roll SPIRV-Tools and temporarily use Vulkan SPIRV validation 

New additions to the validation for the WebGPU execution environment
broke all the tests that use shaders because tests don't produce valid
SPIR-V for WebGPU and also backends don't know how to lower
WebGPU-flavored SPIR-V to target languages.

Also rolls SPIRV-Headers to a version compatible with SPIRV-Tools
